what are you defining as high sulpher diesel....
the last diesel we had was LSD or low sulpher diesel... at 500 PPM
the new diesel is ULSD or Ultra low sulpher......at no more than 15 PPM
Any 07 or newer truck can run on either fuel....but in 2010 LSD will no longer be availabe anywere. If you have the choice to run 500PPM diesel in your truck i would reccomend it as long as you can get it. I would NOT reccomend running unregulated fuel though, over 500PPM can damage your motor as it wasnt designed to run on anything over that...
